Which pair shows equivalent expressions? 3 (x + 2) = 3 x + 6 3 x + 2 x = x squared (3 + 2) 3 x + 2 = 3 (x + 2) Negative 3 (2 + x

kogti [31]

Answer:

The first pair shows equivalent expressions.

Step-by-step explanation:

3(x+2), you would have to distribute 3 among x and 2, also known as expanding the expression. So you'd do 3*x + 3*2, which equals 3x+6

The first equation is 3(x+2)=3x+6

Therefore, the first pair shows equivalent expressions.

-c=p-r
If you were getting the negative C by itself you will want to move the R over on the opposite side. You do that by subtracting are to both sides the hours on the left cancel out leaving you with a negative C on the left side which equals P minus R on the right side

10. Calculate 18% of 75 to one decimal place.

Anarel [89]

First write 18% as a decimal by moving the decimal point two places to the left to get <em>.</em>18.

The word "of" means multiply, so we have (.18)(75) which is 13<em>.</em>5.

Please explain and solve 2/3 = m/42

ivanzaharov [21]

Whatever you do to the numerator you must do to the denominator so 3 goes into 42 14 times so 3x14=42 2x14=28 so 2/3is equivalent to 28/42

The number of dime Jenna have is 15 and the number of quarter Jenna have is 35.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Every evening Jenna empties her pocket and puts pockets and puts her change in a jar.

At the end of the week, she counted her money.

One week she had 50 coins all of them were dimes and quarters.

When she added them up she had a total of $10.25.

Let d be the number of dimes and q be the number of quarters.

Dimes = $ 0.10

Quarter = $ 0.25

Then the equation will be

d + q = 50 ...1

0.10d + 0.25q = 10.25 ...2

By solving equations 1 and 2, we have

d = 15 and y = 35

Then the number of dime Jenna have is 15.
